past the middle ; the intervals are more plane and there is no trace 

 of puncture on the third interval. Length 18 mm ; width 6 mm. 



Hab. Transvaal (no exact locality). 



In general facies this species is not unlike P. congruens, from 

 which it differs in the more parallel shape of the prothorax, and the 

 less oblong elytra. 



Pterostichus alticola. 



Black, shining ; antennae and palpi piceous-black ; head smooth 

 and with two faint frontal impressions : prothorax sub-cordiform, 

 i.e., not much attenuate laterally in the anterior angle, rounded and 

 gradually narrowed to the base, which is about one-half of the 

 width of the median part, basal angle rounded, outer margin not at 

 all recurved ; disk smooth, supra-lateral basal impressions narrow 

 and shallow; elytra elongate, oblongo-parallel, narrowly striate with 

 the striae smooth and the intervals sub-convex, third one with four 

 equidistant punctures. Length 12 mm. ; width 3^ mm. 



Distinct from all the other South African Pterostichus, and easily 

 distinguished by the sub-cordate shape of the prothorax and the 

 more linear facies. 



Captured on the summit of the Giant's Castle, Basutoland, in the 

 Drakensberg Eange, at an altitude of 8,500 feet. 



Pterostichus inordinatus. 



Black, shining ; elytra opaque, palpi and tarsi piceous-red ; head 

 smooth and with the supra- ocular rounded ridge very prominent, and 

 with two median impressions in the frontal part between the eyes 

 alongside the raised supra-ocular ridges ; prothorax nearly parallel 

 but a little narrower at base than apex, where it is straight but with the 

 outer angles projecting, the base is very slightly sinuate, the outer 

 margins carinate and not recurved behind, the outer angle is sub- 

 obtuse, but not rounded, the upper part is smooth, plane, but a little 

 sloping in the anterior lateral part, and the basal impressions are 

 wide ; elytra nearly oblong, but very slightly wider past the median 

 part than at the base, wiiich is sinuate, slightly aculeate at the 

 humeral angle, while the shoulder is sloping for a very short dis- 

 tance ; the outer margin is sharp and recurved for two-thirds of the 

 length, and the dorsal part is carinate with the third, fifth, and 

 seventh carinae more raised than the others ; the intervals are finely 

 and closely aciculate, and the series of punctures in the anterior and
